Abstract

This paper studies the problem of Zero-Knowledge Protocol (ZKP) and elliptic curve cryptographic implementation in a computationally limited environment, such as, the smart cards, using Java Card. Besides that, it is explained how the zero-knowledge protocol was selected to implement it on a smart card and how the benchmarking was conducted to select this protocol. The paper also shows a theoretical development to implement the ZKP protocol using elliptic curve cryptography.
